Abstract (en)
[origin: US4502797A] Arrangement for a print head having at least one print electrode and being movable relative to a record carrier transported over a support, and pressed down onto the record carrier by the effect of an actuator, where a first frame piece (4) carrying the print electrode (6) supported in a holder (5) is pivotably fixed, via a spring arrangement (2,3) biasing the print head towards the record carrier, to a second frame piece (1) opposite the first frame piece (4), where furthermore an electromagnetic actuator (9, 10) between the two frame pieces is attached to the second frame piece (1) to which a resilient ferromagnetic armature (14) is also fixed and through its greater bias acting against the bias of the spring arrangement (2, 3) abuts against a non-ferromagnetic stop (15) provided at the first frame piece and facing the end of the armature, which thus lifts the print head against the force of the spring arrangement (2, 3), and where by the operation of the actuator (9, 10), the print electrode ( 6) places itself against the record carrier (7) under the force of the spring arrangement (2, 3).
